connect the additional hardisk..
and figured that it is a linux partition…

what should we do to see the files  is ..


vgscan

[root@localhost ~]# vgscan
  Reading all physical volumes.  This may take a while…
  Found volume group “VolGroup01″ using metadata type lvm2
  Found volume group “VolGroup00″ using metadata type lvm2


lvscan  

[root@localhost ~]# lvscan
  inactive          ‘/dev/VolGroup01/LogVol00′ [74.19 GB] inherit
  inactive          ‘/dev/VolGroup01/LogVol01′ [1.94 GB] inherit
  ACTIVE            ‘/dev/VolGroup00/LogVol00′ [2.47 GB] inherit
  ACTIVE            ‘/dev/VolGroup00/LogVol01′ [512.00 MB] inherit


vgchange -a y


lvscan

should see all active. 

mkdir /media/test
mount /dev/VolGroup01/LogVol00' /media/test

cd /media/test


ls
should be able to see all the files..
